 The state highway was relocated and widened near Reisterstown in the late 1930s and along the rest of its route in the early 1950s.The Hampstead Bypass was planned as early as the 1960s to ameliorate the increasing congestion along the MD 30 corridor that was only exacerbated when I-795 was completed to Reisterstown in the late 1980s.However, the construction of the bypass was continually delayed due to environmental issues and politics.
